^This.Yep - I remember them. Salisbury steak and Turkey were the preferred meals.
I think our first microwave oven was the Amana Radarange.The salisbury steak was my favorite. While I wasn't the one heating them up in the oven, I do remember the foil tray.
Speaking of the tray, I also remember my introduction to the microwave oven. A kid up the street re-heated his burrito in a minute and a half. I was amazed.
